Think of it like a recall notice for aircraft, but legally binding.\n\n**What it does:** It requires owners and operators of specific **Beechcraft Baron aeroplanes** (models 95-B55, 95-B55A, E55, E55A, 58, and 58A with certain serial numbers) to take corrective action on their **wing strobe lights** if they have specific Hoskins or Grimes brand lights installed.\n\n**Who must act:** Anyone who owns or operates these specific Beechcraft aircraft with the affected strobe light part numbers.\n\n**What action is required:** Follow the instructions in **Beechcraft Service Instruction No. 0800-362** (a technical document from the manufacturer). This typically involves inspecting, modifying, or replacing the wing strobe lights to prevent potential safety failures.\n\n**When it must be done:** Within **100 hours of flight time** after **31 March 1977**.\n\n**Why it matters:** Wing strobe lights are critical safety equipment that make aircraft visible to other planes, especially in low-light conditions. This directive addresses a specific defect or safety concern with certain strobe light models that could fail or cause other problems.\n\n**Good news for early adopters:** If an aircraft already complied with the original version of this directive (issued in March 1977), it automatically satisfies this amended version — no need to do the work again."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":false,"description":"The amendment requires the same corrective action as specified via Beechcraft SI No. 0800-362 for the identified aircraft and strobe lamp part numbers and retains the original compliance effect: aircraft that complied with the original issue still satisfy this amendment (Note).
